Polysulphate helps make more of melons

Results from a recent research trial with melons in Indonesia report a remarkable range of benefits from the use of Polysulphate fertilizer. 

Hitting high quality targets

Those of us who consume melons enjoy them for their refreshing flavour and delicious texture. The melon farmers and growers who produce these popular fruit measure those criteria too. But they also must monitor and choose to change the agronomic practices – including crop nutrition - to cost-effectively combat disease and other problems to achieve excellent yield and quality they and their customers want. Farmers of melons in East Java, Indonesia, are being encouraged to review what they do in the light of the results from a recent crop nutrition experiment with melons.

The driver for the research

To aim of the research was to evaluate the effect of Polysulphate fertilizer as compared to the farmers’ practice on the yield and quality of melon. This trial consisted of two treatments. One had the farmers’ usual practice of liquid fertilizer every 5 days as the control. The second treatment combined that farmers’ practice with Polysulphate applied to the soil 5 days after planting at 40 g/plant (680 kg/ha).

Proof that optimized fertilizer strategy brings rewards

Providing the key nutrients contained in Polysulphate not long after planting, which are released to the crop over a prolonged period, provided major benefits to melons. Those running the trial were able to observe and measure several significant changes in the melon crop including:

  • Melons treated with Polysulphate showed more uniform growth than the control.
  • There were no cracked fruits amongst the Polysulphate-treated melons.
  • Disease incidence decreased by an impressive 47% with Polysulphate fertilizer.
  • Melon fruit were 8.7% heavier in the Polysulphate-treated plot.

These results are added to the library of evidence of the researched benefits of Polysulphate to crops around the world.

The experiment library continues to help to guide farmers and other decision makers on how best to adjust fertilizer strategies to optimize crop productivity. This is all to the benefit of farmers and of course consumers who enjoy, literally with melons mentioned here, the ‘fruits of their labour’.
